💡 Did You Know?
- SUVAT numericals in every competitive exam
- v-t graph area questions — asked yearly since 2005
- Free fall with initial velocity — 12× in JEE/NEET
- Relative velocity — zero skips in BITSAT
- Numericals = ~80% of chapter marks
Key Takeaways
Three SUVAT equations cover all 1D kinematics
Know which two variables are unknown — choose the right equation.
Area under v–t graph = displacement
Area above x-axis = +ve displacement; below = –ve.
Slope of x–t graph = instantaneous velocity
Concave up = accelerating; concave down = decelerating.
Free fall: a = –g = –9.8 m/s²
Taking upward as positive: at max height, v = 0.
Relative velocity v_AB = v_A – v_B
For same direction: |v_A – v_B|. Opposite: |v_A + v_B|.
nth second formula: s_n = u + a(2n–1)/2
Distance in nth second — frequently tested in JEE.
